expedite a passport

I've never been to expedite a passport.

I just found out that we will be traveling overseas in about 6 weeks. Thankfully I pulled out my passport for the number to book airline tickets. That is when I noticed it expires in four months. This is not really enough time left on it to travel overseas. I will be going in the morning to have it renewed. I am not sure yet whether it is worth it to have it expedited or not. My friend told me per the passport office that non-expedited passports are taking four weeks while expedited ones take three! To me that does not make it worth the extra money. I just want to make sure it's here in time!

That I'd like to see.
